GRArN-SE PABATOR.

Be it known that I, NED HUFF, a citizen of the United States, residing at Jackson townshipfin the county of Wells and State of Indiana, have invented certain new and useful Improvements in Grain-separators; and I do declare the iollowinfr o be a full, clear,

and exact description o? the invention, such as will enable `others skilled in the art tov which it appertains to make and use the same.

My invention has relation to new and useful improvements in grain separators for v separating grain from the straw and has for its obj ect the production of a comparatively simple and efficiently operating device of this character by means of which grain may be separated'from straw in an improved and expeditious manner without danger of the separating apparatus becoming-deranged or inoperative.

With the foregoing andA other objects in view which will appearas the nature of the invention is better understood, the invention consists in certain novel features of construction, combination and arrangement of parts as will be hereinafter fully described and claimed.

In the accoml'ianying drawings, Figure 1 is a central longitudinal sectional view of a grain separator constructed in accordance with my invention; Fig.v 2 is a horizontal sectional view on the line 2-2 of Fig. 1; Fig. 3 is a cross sectional view on the line 3-3 of Fig. 1 looking in the direction of the arrows; `Fig. 4 is a similar view looking in the opposite direction; and Fig. 5 is a detail perspective view of the adjustable separating grate.

Referring now more particularly to the drawings, the numeral 1 represents the frame of the machine and 2 and 3 represent respectively a cylinder and drum beater journaled transversely in thefront end of the frame.

The numeral lire resents the ad'ustable separating grate whic 1 is composed oli two independent-separating members 5 com rising each a plurality of longitudinal paralle :grate bars 6 through which pass a plurality of parallel grate bars 7 arranged at right angles therewith, the upper edges of said b ars 6 extending a suitable distance above the grate bars 7 and are corrugated so'as to coact with the teeth of the cylinder and drum-in separating'the grain irom the straw. In the application of Specification of Letters Patent.

Patented April 21, 1908.

my invention, one of said separating members is arranged under the drum beater 3, is hinged at its outer end by a transverserod 8 or other equivalent means to the side walls of the frame and is hingedly connected at its inner or opposite end to the upper end of the other separating member arranged in an oblique position to work under the cylinder by a transverse rod 9 or other equivalent means.

T he lower lend of said last mentioned separating member is adjustably secured to the.

side pieces of the frame by supporting rods 10 secured at their inner ends to the lower end and at or near the sides oi said member and working through horizontal guides 11 extending ,inwardly from the side pieces of the frame, the free ends of said supporting rods being threaded to receive thumb-nuts `12 and having arranged thereon between said nuts and said horizontal guides coiled springs 13. Rods 14 are connected at their inner ends to or near the ends of said transverse rod 9 work through suitable guides i5 extending inwardly from the side pieces of the frame are threaded at their free ends to' receive thumb nuts 16 and have disposed thereon between said guides and thumbl nuts coiled springs 17. By constructing said adjustable separating grate 4 and securing it in position in the frame in the manner I have shown and described, said grate wild readily adjust itself to different volumes of straw passing between the cylinder, drum beater and the-same and the danger of the grate becoming deranged or inoperative by any foreign object passing into the machine is reduced to a mminnim.

The numeral 18 represents a separating rack arranged longitudinally in the frame, said rack comprising a plurality of corresponding u per rack members 19 arranged at asuitablle angle andconnected at their lower ends or cast with a lowem horizontal rack member' 20, each of said ripper rack members 19 comprising side pieces 21 having arranged across them equal distances apart a plurality of transverse parallel slats 22 and a parallel series of toothed separating bars 23 ,secured to-and arranged at ri ht angles with said slats. The lower horizontal rack member is also provided with-side pieces 24 having arranged across them a plurality of transverse'parallel slats or bars 25 which' plate lwhich is secured in rate the which is'arranged to work in and longitudinally of the'frame and is connected to the front end of the lower horizontal rack member 20 -by arms 27 loosely connected near their upper and lower ends to lugs 28 extending diagonally from the sides of said lower rackniember 20 and grain pan 26, pivoted near their centers to 'a' transyerse rod journaled in the frame of the machine and connected at their lower ends to the connecting bars or members 29 extending Jfrom the frame below the grain pan. The rear end of the grain an is connected to the sides of the lower raclr member by links or bars 80.

31 represents a plurality of parallel lifting arms orfmgers pivotally connected to the upper ends of each of said u per rack members 19 of the separating racli '18 by a transverse rod 32 journaled thereto. Rods 33 havingsockets intheir lower ends are secured near the ends of said transverse rods 32 and working in the sockets of saidrods are extension rods 34 which are adjustably held in position by set screws 35 or other equivalent means. The lowerv end of said exten- -sion rods are connected in any suitable manner to the inner ends of connecting rods 36 extending longitudinally of the grain pan rand adjustably connected at their outer ends to the sides thereofyin any suitable manner. The numeral 37 represents a deflecting any suitable manner near the front* end of the se arating rack 18 and is arranged'transyerse f therewith, said late serving todefleet the grain senal rater from the straw by means of said oy inder, drum beater and separating grate into the grain pan.

In the operation of my invention, straw is i fed in the machine at its front end and passes between the cylinder, drum beater and adjustable separating grate which se arain from the straw which strilfes against t edeflecting late and is rdeflected into the' grain an. aid adjustable separating grate wil readily adjust itself to the volume of straw and liabilit of th'e same becoming broken or damagedY volume of straw or by some foreign object is reduced to a minimum. The straw passes from the separating grateto the upper rack j members 19 of the separating rack 18 which rear of the machine.

quickly carry 'off the long straw,y the short straw 'and chaff falling throuvhthe rack members and liftino' arms or ingers 31 to the lower rack member 20. When the separating rack 18 is moving toward the cylinder and separating grate, the grain pan is moving in the opposite direction and the free ends of the lifting arms or lingers are raising 'and serve to raise any long straw that has fallen between the rack members 19 to the The desired amount of movement of the lifting fingers may be regulated by adjusting the extension rods 34 thei fr by .too large a drum beater journaled in member section,

the relative angle between ee or upper ends of the upper rack members and liftingarms or fingers 19 and 31 respectively may be secured by adjusting the free or outer ends of the connecting rods 36 along'the side of the grain pan.

Having thus described my invention, what I claim as new is 1 1. A. grain separator of the character specified, embracing a frame, a toothed cylinder journalcd in one end thereof, a toothed drum beater journaled in rear of the cylinup or down and der, a grate member! section ivotally supi end un er the drum eater, said section comprising a plurality of longitudinally and transversely disposed spaced grate bars, the outer edges of the former being corrugated and disposed 4in a plane above the latter and a second. similar grate member section arranged under the cylinder, said last mentioned section bein pivotally connected at its outerf. end with the frame and loosely connected at its inner end with the inner end of the first mentioned grate member section and yieldahle su i parting means for the connected ends of t.ic grate member section and also for the second mentioned gratte section.
